Translation of scaffold in Spanish

We drove to the hotel Rex where we made reservations in advance. However, once there, two American guys told us that they had a voucher from a travel agent and the price was like half of it.
Due to jet lag (for us it was 10p.m.) we could not sleep, so we stayed at the airport until the morning where we had to take a flight around 8a.m. The destination was Siem Reap in Cambodia.
The next day we decided to spend on the other side of the mountain range (antiplano), in Bolivia. We didn't have the courage to drive deep into Bolivia, as everyone told us about the bad infrastructure and condition there.
